Now, journalists want to paint Greenspan as a great free-marketeer, as if he spent his career fending off cries for more financial regulation. In fact, there was a consensus in the 1980s that inter-state banking had to arrive and that the Glass-Steagall separation of investment banking from commercial banking was being eroded by innovation. The deregulation that ratified these changes would have happened under any conceivable Fed chairman at that time. Moreover, the deregulation was accompanied by what banking officials were convinced at the time were stronger and more effective regulations regarding safety and soundness. They were particularly proud of risk-based capital regulations, and it was the market-oriented economists of the Shadow Regulatory Committee who warned that those were not adequate to prevent a crisis.

This is from Arnold Kling, “The Greenspan Fed,” October 11, 2016.
